Surgical resection of the primary tumor improves survival in patients with locoregional stage T1 nasopharyngeal carcinoma: a propensity score-based matched analysis
Abstract:Background Surgery at the primary site of nasopharyngeal carcinoma (NPC) remains controversial. This study aimed to investigate the efficacy of surgery in patients with stage T1N0-3M0 NPC.Methods We reviewed 1803 patients with newly diagnosed stage T1N0-3M0 NPC from the Surveillance, Epidemiology, and End Results (SEER) database for the period 2004–2015. The Kaplan-Meier method and propensity score matching (PSM) analyses were used to compare cancer-specific survival (CSS) and overall survival (OS) between su… Show more
